  • Abstract
    Anisotropic etching of tungsten submicrometre features has been achieved with an electron-cyclotron-resonance-generated SF6/Ar plasma. The process is suitable for W Schottky gates for highspeed, high-power GaAs transistors. Tungsten gate sidewall profiles are evaluated as a function of RF bias
